Shifting Two Anymarks with One Pistion

to save more weight and air you could use servos to shift


also i was thinking about somehow shifting two with on small motor if we get a small enough one in the kit?

I have to say, I'm not entirely a fan of shifting with servos. I would want my drive train to be the most durable, reliable, and least complex mechanism possible. The added complexity and small (easily breakable) parts of servo shifting makes me a little nervous. Now, I have to say: I've never actually tried servo shifting, but have done pneumatic to much success.

Anyone wanna weigh in on servos?

we used them on our 2007 robot and they worked good(not as well as the pnuematic shifting though)enough to allow the robot to do wheelies,

using servos would be less complex,I've never had a servo break before,


and you could probobly replace that piston with a single, small, motor(like the fischer price maybe) and shift both(dont know if this would work any better but the idea is out there now)

it saves more air for use because i think we used 1 inch pistons to shift in the past not 1/2

Team 968's 2004 robot was successful with this idea. Pic. I think it saves weight more than it saves air.
